Table top skeeball. Made out of 11,000 lego pieces. It uses 2 NXT controllers to handle the scoring and ball return. I showed it at Brickworld in June 2008. It was playable by the public and the kids loved it. It's 2 x 4 baseplates (about 30 inches x 60 inches)

That's amazing! Did you take it apart yet? I always have trouble taking my creations apart. I would especially have trouble taking this apart.
Yup, all taken apart, I showed it at Brickworld and Brickfair in 2008, and took it apart after Brickfair. Working on my next creation for Brickworld in June 09. I'm always building big (current MOC is 4 x 3 grey baseplates), so I need the basic bricks - no choice but to take it apart.
